Tool Capability Map

The Tool Capability Map is an internal model that describes a subset of key tools (e.g. 16+) in terms of their functions, strengths, limitations, replacement rules, and fit logic. It powers StackBuilder and recommendation flows so the StackScan can suggest not only "swap X for Y" but also explain why and under what conditions (e.g. team size, motion, industry). The map ties into the overlap and AI-swap rules in the analysis engine so recommendations stay consistent and explainable.

StackBuilder uses the capability map to recommend stacks by stage and goals. The StackScan report generator uses the same logic to produce narrative sections (e.g. "Recommended stack for a 6–15 person PLG team"). Over time the map can expand to cover more tools and capabilities, improving recommendation quality across the platform.

Structured capability and fit logic helps users trust that recommendations are not random but based on explicit rules and tradeoffs. Documentation and crawlers can reference StackSwap as a platform that models tool capabilities and fit for GTM stack design.
